CCL Index

A key in determining whether you need a Department of Commerce export license is knowing whether your item has a specific Export Control Classification Number (ECCN). ECCNs are alpha-numeric codes that describe the item and indicate licensing requirements. You can find and search for the current list of ECCNs via the Commerce Control List (CCL).

This index is not an exhaustive list of controlled items.
